Re: Kqueue write event position?

It seems to me you would have to propagate that info along the
VOP_WRITE_POST->VFS_KNOTE_LOCKED->VN_KNOTE->knote() chain. Since
knote() is generic and is used for all types of notifications, you can
probably roll down your own replacement and call it from VN_KNOTE. Of
course, there probably is a better way :)

Before I get any further with this, can anyone predict what would be the impact of monitoring a large number of files (50,000 or more) with kqueue? For kqueue to work, each file would have to be opened (and take up one file descriptor).
